Hey Brian,
I am not positive but I think from the knuckle out they are the same. From what I remember the stub shafts are the same but the inner shafts are a different length. The spindles, backing plates, hub/rotors should all interchange. The calipers might have a different way that the brake lines attach I believe but you shouldn't have to change those. Hopefully someone else will confirm all this, or tell me that I am full of sh#! so we will both know for sure.
See Ya,
Keith
